I just installed UltraISO on an AMD system running Win7 x64 Pro and I'm having the exact same issue with burning. I installed both trial versions 32 and 64bit of PowerISO and have no problems burning images with their software.. UltraISO is a 32bit program and running on a 64bit OS I think is where the problem lies dealing with the SATA AHCI. But how do you fix this... Any help would be greatly appreciated.
I tried to make a Hiren's boot cd with UltraISO on a blank DVD... but it doesn't work. Â The software that comes with windows... isoburn.exe WORKS, PowerISO also works but UltraISO and Nero Burner Rom 32bit both fail to burn on a 64bit OS.
